Title: Improvements in or relating to radiants for gas-fires
IPC: F24C15/24
Filed: 1937-07-01
Abstract: 498,230. Radiants for gas fires. MAIN, Ltd., R. & A., and WORTLEY, G. W. July 1, 1937, No. 18330. [Class 126] A tubular radiant with a reticulated front wall has on the inner face of its front wall and/or back wall one or more rows of projections 15, 20 extending along the length of the radiant, each projection being arcuate in contour in side elevation and having a base which is great in length compared with the height of the projection and a thickness which is comparatively small, so that the projection is of flattened shape. Figs. 5 and 6 show respectively the front and rear parts 10, 11 of the radiant which are formed separately from plastic fireclay and brought together before being baked. The projections 15 on the rear wall are integral with longitudinal ribs 12. The projections 20 on the front wall are inclined to one another. Small transverse ribs 21 are interposed between adjacent pairs of ribs 20. The back part 11 of the radiant has openings 13, 14. The rear face of the radiant has depressions 17 separated by ridges 18, and two ridges 19 extending across the radiant above the openings 14. These ridges 19 are shaped to make good contact with the firebrick back, so that air cannot flow past them up the back of the radiant but must pass through the apertures 14, into the interior of the radiant. The front and back walls of the radiant converge upwardly. Some dimensions are given. According to the Provisional Specification, an additional slot may be provided in the rear wall near the top.

IPC: E01C13/06
Filed: 1923-07-16
Abstract: 223,295. Lloyd, M. G. July 16, 1923. Continuous paving.- Tennis and like courts are made by casting concrete, asphalt, or other plastic material between collapsable partitions 18, 19, Figs. 2 and 3, then removing the partitions and filling in the spaces with plastic material, the upper layer of which may be coloured to form the marking lines. The partitions consist of angle-irons connected by bolts and slots; for long lengths, the joints of the angle-irons are staggered as shown in plan in Fig. 3. The layers 23, 24 of material are laid and levelled off flush with the upper edges of the partitions and then compressed by a tool such as that shown in Fig. 4, leaving a shallow space for the surface layer which may consist of cement and rounded sand grains, as described in Specifications 182,833 and 191,452. Or the material may be levelled off at a higher level than the partitions by means of a screening board and then be compressed by a lcng roller.

Title: A shutting-off valve for bomb shelters
IPC: F16K17/04
Filed: 1966-04-27
Abstract: 1,135,585. Valves. B. A. ELIASSON. 27 April, 1966 [29 April, 1965], No. 18384/66. Heading F2V. A valve for closing an air vent in a shelter in the event of an explosion comprises a tubular valve member 13 closed at its inner end and open at its outer end. The valve member is slidable in a cylinder 7 and is loaded by springs 23, 24 to a position in which ports 17 in the valve member are aligned with ports 18 in the sleeve to allow flow through the valve.

Title: Recovery of phenols
Inventor: JACOBS DAVID IAN HUTCHINSON
IPC: C07C39/08
Filed: 1953-07-04
Abstract: Resorcinol is manufactured by the process comprising the catalytic decomposition of a reaction mixture containing m-diisopropylbenzene dihydroperoxide together with small amounts of m-diisopropylbenzene monohydroperoxide and/or m-(2-hydroxy-2-propyl)-a ,a -dimethylbenzyl hydroperoxide followed by distillation of the decomposition reaction product in the presence of a high-boiling inert substance which is substantially inert to resorcinol and removal of resorcinol from the distillate, characterized in that the distillation residue is treated for the recovery of m-isopropyl- and m-isopropenylphenols and is subsequently recycled to the decomposition reactor or to the still. Suitable high-boiling inert substances are a gas oil fraction (boiling between 100 DEG  and 200 DEG  C. at 100 mm. Hg. pressure), triisopropylbenzene, methyl -, chloro -, and bromonaphthalenes, 1 : 2 : 4 - trichlorobenzene and chlorinated diphenyls.  After crystallization of resorcinol from the distillate, the residue containing m-isopropyl - and/or m - isopropenylphenols is either (a) extracted with dilute aqueous alkali solution (e.g. sodium hydroxide); or (b) treated with an acid catalyst such as an acid clay or mineral acid to polymerize the m-isoproperylphenol.  The alkaline extract from procedure (a) is treated with mineral acids or carbon dioxide to precipitate the mixture of phenols which is then fractionated. Meta-isopropylphenol may be separated, together with the inert substance, from the polymer of m-isopropenylphenol obtained by procedure (b) by distillation, and is separated from the distillate by procedure (a).  Suitable acid clays for use in procedure (b) are acid activated montmorillonites, bentonites, fuller's earths, vermiculites, attapulgites, kaolinites and illites. In examples (1) and (2) the decomposition product from crude m-diisopropylbenzene dihydroperoxide is distilled with methylnaphthalene and then treated by procedures (a) and (b); (3) a mixture of m-diisopropylbenzene mono- and di-hydroperoxides is distilled with a chlorinated diphenyl, the distillate residue being extracted by procedure (a).

Abstract: 147,033. Schr÷ter, F. Jan. 29, 1914. [Convention date]. Vacuum tubes.-A vacuum tube for use as a protective device for power circuits contains one of the rare gases such as argon, neon, and helium, and has electrodes of metals having a small cathode and anode drop such as alkali metals or alloys thereof. The electrodes are arranged at such a distance apart that the discharge can take place at between 70 and 280 volts, a distance of 3 mm. being mentioned as suitable. To promote the formation of alkali metal vapour and thereby reduce the starting resistance, the electrodes may consist of small baskets of brass wire gauze filled with alkali metal, or of sheets of brass wire gauze coated with alkali metal. The tube mav be arranged to earth or switch off the mains by means of an electro-magnetic switch. The metallic vapours formed from the electrodes combine with impurities and keep the gas pure.

An ionization chamber, for use in conjunction with a source of beta radiation, made from aluminium or other material of equal or lower atomic number and provided with a window for the entry of radiation has its inner surface which is exposed to radiation coated or lined with lead or lead paint. A coating of red-lead may be painted on the surface or metallic lead may be sprayed on. Alternatively a layer of lead foil may be used. The layer is preferably of slightly greater than semi-infinite thickness, i.e. half the minimum thickness which will prevent the passage therethrough of any beta radiation. The chamber is rectangular in form or may have curved walls to increase the ionization due to back-scattering of the radiation inside the chamber. The coating or lining has the effect of increasing the output of the chamber.
